Ecohealth does not report on human environmental health issues in the rivers, such as drinking water quality.

Over a 12 month period and using the combined resources of Council, Office of Environment and Heritage, Local Land Services, Department of Primary Industries and the University of New England, (also Kyogle, Coffs, Guyra, Tenterfield and Bellingen councils) we collected data from 88 sites in 37 individual river systems in the Clarence catchment.
